il '0 all whom it may concern:

Be it known that I, BENJAMIN F. BEAVER, a citizen of the United States, residing at Hutchinson, in the county of Reno, State of Kansas, have invented certain new and useful Improvements in Flying-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to'which it appertains to make and -use the same.

This invention relates to new and useful improvements in flying machines, and par-- ticularly those of the heavier-than-air type.

The primary object of the invention resides in the provision in an aeroplane of means whereby the supporting plane may be actuated to assume such position as to form a parachute, so that in case accident should occur, a arachute may be formed by the .body of t e machine wherebythe operator may safely descend.

A further object of the invention resides in the provision inan aeroplane of the class described of means whereby that mechanism which is operated to adjust the planes to. form the parachute, also serves to move the various planes so that the machine is enabled to maintain its equilibrium.

A still further object resides in the provision of an aeroplane of the class described, which is efficiently braced to form a strong and durable structure.

\Vith these and other objects in view, the invention resides in the novel combination, formation and arrangement of parts to be more fully hereinafter described and illustrated in the accompanying drawings and particularly pointed out in the claims hereto appended.

. Reference is had to the accompanyin drawings wherein similar characters of re erence designate corresponding arts throughout the several views, and in w ich:

Figure 1 is a perspective view of the machine, with its planes in normal relation, Fig. 2 is a central vertical longitudinal soctional view taken through the machine. Fig. 3 is a transverse vertical sectional view through the machine, and Fig. 4 is a perspective view of the machine with its wings folded toforrn a parachute.

Referring now more particularly to the accompanying drawings-5 designates four corner uprig ts of the frame of the aeroplane. The tops of these uprights are connected by the rigid supporting plane 6 and the lower endof the uprights are connected by thesills 7. Carried by the sills 7 are suit able flooring members 8 on which is mount ed an en inc 9. Extending from the floor ing mem r to the top plane 6 is a central vertical standard 10 and journaled in :1

- bracket 11 on this standard is a shaft 12 which extends outwardly of the aeroplane frame and carries at said outer end a propeller- 13. This outer end of the shaft is 3ournaled in a bearin 14 carried by arms 15 extendingdiagon ly u ward from the Pivotally secured to Eli-20 and disposed I between the front and rear pairs of uprights 5 are front and rear elevators or lifting planes 21 and'22 respectively. These planes are of such size that they serve also as lifting planes and they are adapted to be SWUHQ in a direction indicated by the arrows in Fig. 2 so that they substantially close the front and rear ends of the frame. The lower portion of the front elevator is provided with an open-ended slot 23 which receives the propeller shaft 12 when the plane is folded. For swinging these planes. a shaft 24 having fixedthereto a drum 25 is journaled in suitable brackets 2C disposedforwardly of the seat 18. Pullevs 27 are can ried by the front and rear ends of the plane 6 and pullevs 28 are carried by the horn; and rear ground sills. A pulley 29 is-also carried by the intermediate portion of the standard 10. A cablememher is'secni'ed to the rear end of the rear elevator 22 and is trained under the rear pulley 28, over the pullev 29 and overa pulley 27 and is secured to the forward end of the front elevator 21. I

Thecablc is then trained under the front pulley 28, wound around the drum 25, trained under the pulley 29 and over the rear pulley 27 and is secured to the rear end of the rear elevator 22. Thus upon rotation of the drum 25, the planes are simultaneously swung. To facilitate securing the cable to the forward lifting plane 21, it is split adjacent said frame to form the sections 30 which extend on each side of the slot 23- Pivoted to the uprights 6 at points 31 dis- 'aileron.

posed above the pivotal connections20 are ailerons 32 which are also of such size as to form supporting planes and which are adapted to be swung to close the sides of the frame. For swinging these planes. a

shaft 33 carrying a drum 34 is disposed adjacent and at right angles to the shaft 24 and is journaled in suitable brackets 35.

The intermediate portion of the sides of the to idplanefi. carries pulleys 36 and the ate portions of the side sills 7 'interm carry pulleys 37, #Atcable 38 is secured to the outer e ge of one aileron 32 and extends under the adjacent pulley 37 and is wound around the drum 34 from whence it extends and is trained around the other pulley 37 and secured to the inner edge ofthe other aileron. The cable is .then trained around the pulleys 36 and has its end secured to the outer edge portion of the first-mentioned From the foregoin it is observed that upon rotation of the. rum, in either direction the plane 32 will be swung simultaneousl to maintainthe' lateral equilibrium of t e machine. Upon rotating the drum.

in a clockwise directionit is observed that the planes 32 will swing in a direction indicated to close the sides of the machine.

The shafts 24 and 33 are provided with crank handles 39 and it is observed that by simultaneously rotating these crank handles, the planes 21 and 22 and the planes 32 will be swung to form with the rigid plane 6 a parachute whereby the machine and operator may safely descend. The crank handles also control the planes in their normal operation.

To brace the planes 32 in such manner as nected to the I Guy wires 44 are extended from the uprights 5 to the upper portions of said brace bars.

From th foregoing it is observed that "an aeroplane has been provided which is strong and durable and readily controlled in its normal operation and which has its movable planes so-mounted that they may be readily swung to form a parachute.

It is not desired to limit this invention to any of the details of construction shown and deseribed as it will be understood that various minor changes and ,modificatjons within the scope of the appended claims may ,be made without departing in any manner from the spirit of the invention.

What is claimed 1s:

1. An aeroplane comprising corner uprights, a-top plane connecting the upper ends of the uprights, sills connecting the lower ends of the uprights to form a frame, a propeller shaft carried by the frame and extending outwardly of one end thereof be tween a pair of end uprights, elevator planes pivoted between the pairs of end uprights, means for swinging said planes and the plane adjacent the propeller shaft being provided with a slot for receiving the propeller shaft upon swinging the planes.

2. In an aeroplane, the combination with a frame including a pair of uprights and a top member connecting the v uprights, of a plane disposed between and pivoted to the uprights and provided with-a central cutaway portion, a shaft carried by the plane and extendin across the cutaway portion and a brace ar having its upper end inwardly directed and secured to the top member and having its lower end inwardly directed and pivoted to the shaft.

In testimony whereof, I afiix my' signature, in the presence of two witnesses.
